When it comes to semiconductor technology, remarkable developments have been made. These developments have led to efficiency in switches and overall running if electronic devices. Solid state switches were built to replace thyratrons and spark gaps. Also use of TTL input has become common and it makes it easy to use switches. There are important factors that should be noted when it comes to a high voltage contactor.
One of these details is the low input power loss. This low loss has been making possible through the use of MOSFET technology when developing the switches. The only loss incurred in this technology is only caused by the total gate charge, the drive voltage, and switching frequency. The loss is very low since the overal gate charge is small. Switches that use bipolar transistors such as BJT tend to cause more losses. There is a lot of power lost especially during switching.
The contactors are reliable when it comes to high current applications. Even when short circuited, they guarantee steady hard saturation which is very necessary when running high current applications such as medical test equipment. The fact that they are able to switch faster also make them efficient for use in these applications. The switching speeds generally increase the efficiency of the equipment.
It is possible to easily customize these switches in a number of ways. This may include the housing and footprint. The sensitivity can also be customized as per customer needs. This customization helps to suit applications where the switches are being used. They are also easy to use due to the galvanic isolation with TTL control.
The switches are designed to prevent against overload or voltage reversal. Cases of voltage reversal are common and they lead to catastrophic events. The technologies used in these switches make them safe for everyday use. The technologies include MOSFET, IGBT, SCR, and thyristor. With such technology, these contactors are highly recommended.
These contactors are voltage controlled unlike those controlled by current. This helps them to switch using very little current which means they can handle high loads without heating. On the other hand, other switches require a fair amount of current to switch which makes them create a lot of heat when handling high loads. The possibility of these switches operating in linear mode is very minimal. This is because the level of drain current does affect the gate-source voltage.
These type of switches ensures that there is a faster switching. This is made possible because the switches are able to handle high frequencies. The faster switching also does not leave a chance for much loss. The transistors are insulated with a thin oxide layer which prevents drawing of current during switching. This advantage has a lot of effect on the overall performance of the contactors and the power losses.
There are many developments still being made in the semiconductor technology in order to reduce limitations if these contactors. They are efficient enough to be used in day-to-day operations but still have a few downsides that need to be taken care of. The above-discussed features are just some of the advantages of using these switches. These are sure to make your work easy.
